RAILROAD-TRACK FASTENING.

SPECIFICATION forming part of Letters Patent No. 656,661, dated August 28, 1900. Applicati0n f 'lled J ly 9, 1900. Serial No. 22,980. (No model.)

To all whom it may concern.-

Be it known that I, LEANDER D. RALS'ION, a citizen of the United States, residing at North Lawrence, in the county of Stark and State of Ohio, have invented certain new and useful Improvements in Railroad-Track Fastenings; and I do herebydeclare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My present invention relates to track-fastenings, has for its object efficient means for securing the rails of the track to the crossties, and consists in certain improvements in construction which will be fully disclosed in the following specification and claims.

In the accompanying drawings, which form part of this specification, Figure 1 is a perspective showing two rails secured to crossties; Fig. 2, a vertical transverse section through one rail, a crosstie, and the fastening devices; Fig. 3, a bottom plan view of the same; Fig. 4, a vertical transverse section through a cross-tie and the locking-key; Fig. 5, a vertical longitudinal section through the upper side of a cross-tie, showing the support for the locking-key in side elevation; Fig. 6, a perspective of the locking-key detached, and Fig. 7 a side elevation of one of the clamping-dogs.

Reference being had to the drawings and the letters thereon, A indicates the hollow metallic cross-tie, and B the rails, which are arranged in the usual manner of constructing railway-tracks. The ties A are provided with rectangular slots at a at each end thereof and on opposite sides of the rails 13 to receive the clamping-dogs O 0, one of each pair of which dogs engages the Web 11, the flange c, and the lower part of the tread d of the rail closely by corresponding seats 6, f, and 9, while the opposite dog 0' has a seat It to engage the flange, a seat 1; to engage the web, and is rounded at k to admit of insertion of the dog after the rail has been placed in position on the road-bed and the crossties with the dogs 0 in engagement with one side of the rail, and the outer end of rounded portion 71; bears against the lower part of the tread cl of the rail, as shown in Fig. 2. Each clamping-dog is provided with a slot or notch Z on which the key passes, and is held to its seat in the slots or notches n of the clamping-dogs O O by a spring E, one end of which engages the key at q and is secured to the under side of the top of the cross-tie, the spring having sufficient tension to hold the key'normally to its seat and to restore it to its normal position should it be displaced by accident, such as a jar. I

Having thus fully described my invention, what I claim is- 1. In a track-fastening, the combination of a slottted cross-tie, a rail, a pair of clampingdogs having grooves in their adjacent edges and engaging said slots, the cross-tie and the rail; and a locking-key engaging the groove in both dogs. V

2. In a track-fastening, the combination of a slotted cross-tie, a rail, a pair of clampingdogs having notches in both their edges, one of which engages the cross-tie, and a locking key engaging the" notch in the opposite edge of both dogs.

3. In a track-fastening, the combination of a slotted cross-tie, a rail, a pair of clampingdogs having notches in boththeir edges, a locking-key engaging the notches in one edge of both dogs; and a retaining-spring for the key.

4. In a track-fastening, the combination of a slotted cross-tie, a rail, a pair of clamping dogs extending through the top of the tie and having a notch in the outer edge engaging the tie, a notch on the inner edge of the dogs, and a locking-key yieldingly secured in e11- gagement with the notches in the adjacent edges of the dogs.

In testimony whereof I affix my signature in presence of two Witnesses. I

LEANDEB. D. RALSTON.
